The invention discloses high-strength high-thermal-insulation silica aerogel and a preparation method thereof. The preparation method comprises the following steps: modifying halloysite with amino-terminated polysiloxane; adding ethyl orthosilicate, absolute ethyl alcohol, hydrochloric acid, dimethyl formamide and ammonium hydroxide to ensure a reaction and obtain gel; finally, carrying out carbon dioxide supercritical extraction to obtain the silica aerogel. As hollow natural clay fiber halloysite which is high in mechanical strength, low in thermal conductivity and high in thermal stability is taken as a reinforcing phase, the silica aerogel prepared according to the preparation method is relatively high in porosity, relatively low in density, excellent in mechanical property, favorable in heat-insulating property and relatively high in heat resistance.
